As far as I understand, Torvalds said that he is not going to oppose all AI-generated improvements to Linux, not that he's vibe coding new kernel modules for fun.
Linux is definitely going to speed up as it starts to get vibe coded. In a few years, I bet that it's all going to be built with agentic loops, and nobody will be looking at the code at all.
What do you call people who vibe code? When he says that he sees a 10x improvement in productivity with AI code gen, what makes you think he's going to put the tool down? Do you think he's stupid or something?
He'll keep ramping up his vibe coding, because he can see it's the future.
That is fair - but your wording makes it sound like he is going to set aside his brain and let AI tools do all the kernel-related work for him, which I don't think will happen.
As far as I see it, he is vibe coding tools for himself but (hopefully) still manually monitoring crucial bits of software like Linux.
